Pain secondary to knee osteoarthritis (OA) is the most common cause of medical consultation in patients 55 years old and above. Knee OA pain is complex and involves both nociceptive and neuropathic pain. Recent management options have been focused on targeting the nerves of the knee, and to effectively investigate the mechanism and effect of these procedures, it is important to review the types of pain associated with knee OA, specifically neuropathic pain (NP). This article specifically focuses on the available evidence on NP, its prevalence in patients with knee osteoarthritis, outcome measures to determine the presence of NP, and their impact on the present and future management of knee OA pain. The information from this narrative review may potentially help clinicians identify the presence of NP in their patients and further guide them in providing a more appropriate and comprehensive management plan. The outcome measures presented in this review may also be used in future research exploring the management of knee OA pain.

BACKGROUND

Sarcopenia is a multifactorial disease with a progressive decline in skeletal muscle mass, muscle strength, and physical performance. Curcumin is a nutraceutical investigated for its anti-inflammatory and antioxidant properties. It is inexpensive, accessible, and considered a safe and practical approach to help alleviate symptoms of sarcopenia and improve muscle mass and function. Objective: This systematic review aims to obtain more conclusive evidence on the effectiveness of curcumin among adults 40 years and above with sarcopenia in improving muscle pain, strength, performance, and muscle morphology.

OBJECTIVE

This systematic review aims to obtain more conclusive evidence on the effectiveness of curcumin among adults 40 years and above with sarcopenia in improving muscle pain, strength, performance, and muscle morphology.

METHODOLOGY

The review will be conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) Statement. It will focus on any interventional studies on curcumin for adults diagnosed with sarcopenia, with the following outcomes: clinically significant improvement in pain, muscle strength and performance, quality of life, and improvement in muscle morphology. Studies completed until 2024 will be included. The databases to be searched include PubMed, Cochrane Central Register of Controlled Trials (CENTRAL), CINAHL Plus (EBSCOhost), Embase, and Web of Science. The identified citations will be collated in Zotero and uploaded to Covidence© to be assessed using the eligibility criteria and systematically reviewed by two independent reviewers. The CASP Randomised Controlled Trial Checklist will be utilized to assess the quality of the included studies.

EXPECTED RESULTS

The results will serve as a groundwork for future sarcopenia research among allied health specialists, particularly those in the field of physiotherapy - students, healthcare practitioners, and academicians (PROSPERO registration number: CRD42023448750).

Knee pain secondary to knee osteoarthritis is one of the most common reasons for consultation in patients 50 years old and above. Due to limitations of current management options for knee osteoarthritis, studies seeking alternative treatment techniques have emerged, including procedures targeting knee innervation. The effectiveness of nerve hydrodissection for managing neuropathies such as carpal tunnel syndrome has been demonstrated but has not been applied to nerves that innervate the knee to manage osteoarthritis. This article discusses the potential application of ultrasound-guided nerve hydrodissection to the anterior innervation of the knee, known as the genicular nerves, for pain management in patients with osteoarthritis.
